12.3 Kirchoff’s Voltage Law & Current Law

Current Law
Total current into a point in a circuit equals total current out of the same point






A-B gain CurrentIn = I1



B-A loss CurrentOut = I2


C- D gain I1 = I2 + I3


D- C loss I4 = I1

Voltage gain – electric current gain energy from – terminal to + terminal. There is a voltage gain


Voltage loss – go from a position of more energy to less energy
+ to - on battery
